1. Collection of ear strips

Cuttings are generally collected after the leaves fall in autumn, and the dormancy period begins in spring, combined with the winter cutting of the tree body. Generally, annual branches with strong growth are selected, and then fully lignified without disease

2. Cuttings storage

In spring, hardwood cuttings need to be stored in winter. The storage method is generally: cut the branches into a length of about 15 cm, select a place with higher terrain and good drainage, and start digging ditches. Generally, the width of the ditch is 1 meter and the depth is 60 to 80 cm. The length should be determined according to the number of cuttings. First lay a layer of 5cm thick wet sand under the ditch, and then bundle the cut cuttings every 50 branches, and then put them in the ditch in layers. When the cuttings are placed 20cm away from the ground, fill them with wet sand, then cover them with a layer of soil, and insert a handful of grass in the middle to ventilate them

3. Cutting processing

In order to improve the survival rate of cuttings, the cuttings are generally soaked with some running water 6 to 8 days before cutting. If it is stagnant water, the water must be changed. If there are obviously irregular objects at the lower incision, cut again. You can also soak some of this solution for 24 hours, which can improve the survival rate of cuttings

4. Cutting technology

Before cutting, we should carefully prepare the land, and then apply enough fertilizer, so that the soil can become more loose and the water is more sufficient

5. Cutting time

Cutting is usually from March to April in spring, because the soil has begun to melt at this time, and the temperature will be more appropriate at this time. The cutting of tender branches is mostly started in June, and can be picked and cut at any time
